Undertale 2: Overtale

John Undertale carries a burden of guilt that has followed him far past the point where most people would have put it down. When the moment arrives that his friends' lives are at stake, he acts on what he has spent so long building—training under the Undertale Gurus, accumulating the strength needed to face the Bird King, and preventing the devastation that threatens everything he cares about. A fan-made sequel to Undertale, set in motion by internalized guilt and resolved through confrontation.
